Abstract

Background

Data about small area estimates of cancer risk factors are difficult to obtain in Canada. The current study aims to provide an assessment of the prevalence of different behavioral risk factors of cancer at the level of Canadian provinces/territories and sub provincial health regions/units.

Methods

Canadian Community Health Survey (CCHS) datasets for 2017/2018 were reviewed and adult participants (≥ 18 years old) were included. Baseline demographic data and health behaviors (including ever-smoking, current smoking, alcohol drinking in the past 12 months, below-recommended physical activity, and obesity) were reviewed. Prevalence of each of these behaviors within different provinces/territories as well as within each health region was reviewed. Multivariable logistic regression analysis was then done to examine the association between place of residence and cancer risk factors.

Results

A total of 104,636 adult participants were included in the current analysis. For ever-smoking, the highest prevalence was noted in Nunavut (79.7%); for current smoking, the highest prevalence was noted in Nunavut (67.2%); for alcohol drinking in the past 12 months, the highest prevalence was noted in Quebec (89.3%); for below-recommended physical activity, the highest prevalence was noted in Nunavut (51.3%); for obesity, the highest prevalence was noted in Northwest territories (31.5%). Compared to individuals living within a territory, individuals living within a province were less likely to ever smoke (OR: 0.62; 95% CI: 0.54–0.71), currently smoke (OR: 0.51; 95% CI: 0.45–0.59), be obese (OR: 0.82; 95% CI: 0.71–0.95), but more likely to drink alcohol in the past 12 months (OR: 1.41; 95% CI: 1.20–1.65). There is no difference between both categories with regards to physical activity (OR: 1.02; 95% CI: 0.89–1.15).

Conclusions

There is a general province/territory disparity in the prevalence of different modifiable cancer risk factors as well as disparity between individual provinces/health regions in Canada.

加拿大各省、地区和卫生区域之间可改变的癌症风险因素的差异

摘要

背景

在加拿大很难获得关于癌症风险因素的小区域估计数据。目前的研究旨在评估加拿大各省/地区和亚省卫生区/单位层面的癌症不同行为危险因素的流行情况。

方法

审查了 2017/2018 年加拿大社区健康调查 (CCHS) 数据集，并纳入了成年参与者（≥ 18 岁）。回顾了基线人口统计数据和健康行为（包括过去 12 个月内一直吸烟、目前吸烟、饮酒、低于推荐的身体活动和肥胖）。审查了这些行为在不同省份/地区以及每个卫生区域内的流行情况。然后进行多变量逻辑回归分析以检查居住地与癌症风险因素之间的关联。

结果

本次分析共包括 104,636 名成年参与者。对于一直吸烟，努纳武特地区的吸烟率最高（79.7%）；就目前吸烟而言，努纳武特地区的吸烟率最高（67.2%）；在过去 12 个月内饮酒的比例最高的是魁北克（89.3%）；对于低于推荐的身体活动，努勒维特的患病率最高（51.3%）；对于肥胖，西北地区的患病率最高（31.5%）。与居住在一个领土内的人相比，居住在一个省内的人不太可能吸烟（OR：0.62；95% CI：0.54-0.71），目前吸烟（OR：0.51；95% CI：0.45-0.59），肥胖（OR：0.82；95% CI：0.71–0.95），但在过去 12 个月内更有可能饮酒（OR：1.41；95% CI：1.20–1.65）。

结论

不同的可改变癌症风险因素的流行率存在普遍的省/地区差异，加拿大各个省/卫生区之间也存在差异。
